Why are pressure treated beams used?
Because the beams are made from wood, they can decay over time from contact with moisture. If this happens, it will negatively affect the building’s structural integrity. This is why pressure treated, cedar heartwood, and the heartwood of other rot-resistant wood species are used for the beams. However, heartwood is no longer easy to find at a reasonable price. That’s why pressure treated sapwood is the usual choice for beams today, and sapwood is not rot-resistant. Therefore, the wood beams in a pier and beam foundation are often the source of problems.

Why does my basement crack?
Seasonal moisture is a major cause of cracks within the foundations. Soil beds with high clay content create more problems since they support greater moisture retention. The soil expands when moisture seepage is heavy, which stresses the foundation and causes uneven floor sections in the basement as well as sustained seepage along the basement doors. The basement’s sheetrock may also crack.
